This document discusses wikis and their usability in education. It describes early wiki implementations and studies conducted using wikis for educational purposes. The studies found that student participation was low when participation was voluntary but increased when an article contribution was required. Overall, the document concludes that future work with wikis in education needs to increasingly address their usability to improve student motivation and success.
